In both these cases, the 90 degree angle for fixing the pipes'
connection to the wall plate should be shortened so that it
doesn't protrude through the rubber sleeve.
Mounting the central unit
Push in the unit so that the inlet and outlet pipes face up to each
other, and the mounting brackets rest against the rubber grom-
mets. Rest the left mounting of the central unit on it's seating and
then push the right end into its place. Use your hand to support
the central unit and push it's connections into the sealing grom-
mets of the plate Picture 4.
Install the left locking bracket first, and then the right one.
Attach the low-voltage cable to the central unit and then
the cable to the power supply. Picture 5.
Your unit is now ready to be used. Picture 6.

Installing a wall plate with HEPA filter
Use the wall/filter plate as a template for drilling the holes for the
4 screws. Make sure the plate is well fixed to the wall. Use plugs
or expanding fittings if needed. Picture 7.
On the upper ledge of the plate is a connector to a pipe system in
case that the built-in opening isn't sufficient for the whole house.
This pipe system may in practice be as big as desired. It is in
other words independent of the size of the house or apartment.
When installing the pipe system, connect the low voltage cable to
the connector at the back of the fibre plate. Picture 8.
Mounting the unit
Move the unit towards the fibre plate so that the inlet and outlet
pipes mate up and so that the mounting brackets rest against the
plastic. Let the left bracket of the central unit rest against its seat
and then bring the right hand one into place. Support the central
unit with your hand,
and insert the connections into the sealing of the plate.
Picture 9.
Install the left locking bracket first and then the right one.
Then connect the power supply cable of your unit. Picture 10.
Connecting the suction hose
Suction hoses that are available in different shapes and lengths,
are connected either to the built-in suction-box of the Oxy3etage,
or to separate suction boxes in the pipe system. In the suction-
box are two connectors that signal the circuit card of the unit to
start or to stop respectively. Picture 11, 12.
Maintaining and changing the dust bag
Changing the dust bag
Pull out the frame for the bag from the unit and remove the dust
bag. Picture 13.
Install a new dust bag. Place the collar of the dust bag in the
grooves. The fittings of the frame has two positions that either fit
the large synthetic bag or s-bag® antiodour or s-bag long per-
formance. Replace the frame according to instructions.
to the left of it. In the case of the frame being hard to move, it is
probably wrongly positioned. The lid will close easily when the
frame is in its proper position. Picture 14, 15.
Coarse filter
The coarse filter serves as a protection to the vacuum cleaner
engine in the case the bag for any reason should brake, and will
then prevent dust from entering the engine. The filter must then
be cleaned by rinsing it in running water. After cleaning, the filter
must be absolutely dry before using the vacuum cleaner.
Picture 15.
Changing and cleaning the HEPA 12 filter of the Oxy3etage
Twist the locking bracket downwards and remove the lid.
Picture 16.
If the filter is washable, take it out and rinse it. Make sure it is ab-
solutely dry before reinstalling it. A washable filter can be cleaned
about five times. A non-washable one must be changed once a
year. Picture 17.
When refitting the lid, make sure that both studs in the top of the
lid sit correctly, before fixing the locking bracket. Picture 18.

Troubleshooting

The central unit does not start
1. Is the central unit connected to the mains?
2. Check the fuses.
3. Is the low voltage cable connected to the central unit?
4. Are you using the correct suction hose? The original hose has
the correct connectors.
5. The central unit does not start with any of the suction boxes.
Check that the spring-loaded connectors in the box are not
stuck.
6. Is there a break on the low voltage cable or a fault in the
circuit board of the motor? The simplest way to check this
is to short-circuit both connectors in the suction boxes with
a spoon, coin or similar. If the unit does not start, then is a
break in the connection between the central unit and one or
more of the boxes, or a fault in the circuit board of the motor.
To eliminate a break in the cable, short-circuit the low voltage
connector directly at the unit. If the motor starts, there is a
fault in the cable. If not, the fault lies in the unit. Then contact
an authorised workshop.
The central unit does not stop
1. Check the suction boxes, so that the connectors are not
short-circuited.
2. If the central unit still does not stop, there is probably a fault in
the electronics. Pull out the plug, and contact an authorised
workshop.
The vacuum cleaner does not suck, as it should
1. Check that the suction boxes that are not used, are closed,
and that the lid of the bag space is firmly closed, and not
causing a leak.
2. Is the bag full? Change the bag!
3. Is there a leak in the pipes? Check that this is not the case by
blocking the air supply of the suction pipe with the hand. If the
vacuum valve opens, then the pipes are most likely not leaking.
4. Is there a blockage in the pipes? Check first that there is no
blockage in the suction pipe. Then check if there is better suc-
tion in some other suction box. If this is the case, then there is
most likely a blockage in the pipes leading up to the first box.
If the suction is bad in the other boxes as well, then check the
suction directly at the unit. Do like this; Lift the unit from the
wall and feel with the hand if the suction is better at the unit. If
this is the case, there is a blockage in the pipes. Knowing
